My research focuses on the formation and assembly of galaxies in the very early Universe. Together with my research group, I use some of the world's most powerful telescopes (e.g., JWST, Euclid, ALMA) to study these sources in order to reveal their physical properties. Our ultimate goals are to understand when and how the first galaxies formed, how they grew and built up their mass, and how this is all connected to the underlying large-scale structure set out by dark matter.
